Urinary Collection Device With Permeable Membrane For Buried Penis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with limited or impaired mobility face challenges with traditional urination methods, such as discomfort, pain, and hygiene issues with urinary catheters and bed pans, and difficulties with condom-style catheters for buried penises, which are not effective in collecting urine efficiently.
Innovation Solution
A fluid collection device with a fluid impermeable barrier and a fluid permeable membrane, featuring a fluid receiving portion and a longitudinal portion of varying widths, designed to be positioned adjacent to the urethral opening and perineum, respectively, to collect urine effectively while preventing the penis from entering the chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fluid impermeable barrier is used to define a chamber, then urine collection efficiency is improved, but the device becomes more complex
Solution Approach 1:
The device is divided into distinct functional segments: a fluid impermeable barrier defining a collection chamber, a fluid permeable membrane for urine absorption, a longitudinal portion for positioning, and a fluid receiving portion. This segmentation allows each component to perform its specific function efficiently while maintaining overall system coherence.
Solution Approach 2:
The device combines different material properties in a single structure - using both fluid impermeable materials (for the barrier and chamber definition) and fluid permeable materials (for the membrane). This composite approach enables simultaneous urine collection efficiency and proper fluid management.
2Quantity of substance
If the fluid receiving portion has a larger width than the longitudinal portion, then urine reception capacity is improved, but the device fits less comfortably in the perineal area
Solution Approach 1:
The device exhibits varying widths at different locations: the fluid receiving portion has a larger width to maximize urine reception capacity, while the longitudinal portion has a narrower width to fit comfortably in the perineal area. This local variation in dimensions optimizes both collection capacity and user comfort.
Solution Approach 2:
The device transitions from a two-dimensional planar view to a three-dimensional configuration, where the fluid receiving portion extends laterally to provide broad urine reception area, while the longitudinal portion extends anteriorly to fit the perineal anatomy. This spatial arrangement resolves the contradiction between capacity and comfort.
3Reliability
If a fluid permeable membrane is used across the opening, then urine direction control is improved, but the device becomes more complex
Solution Approach 1:
The fluid permeable membrane acts as an intermediary element between the external environment and the collection chamber. It selectively allows urine to pass through while blocking other substances, providing reliable urine direction control through a simple yet effective intermediate layer.
Solution Approach 2:
The device employs thin film structures (the fluid permeable membrane) that can be easily integrated into the device architecture. These thin films provide effective urine direction control without adding significant complexity or bulk to the overall device structure.
4Adaptability or versatility
If the device is designed for buried penis, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The device is designed with universal applicability for both buried and non-buried penises through its modular components and adjustable positioning features. The longitudinal portion and fluid receiving portion can be positioned to accommodate different anatomical configurations, providing adaptability without requiring precision manufacturing for specific body types.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a comfortable and efficient means of urine collection, even for individuals with buried penises, by maximizing fluid reception and minimizing leakage, with the fluid permeable membrane ensuring that urine is directed into the collection chamber, and the suction system facilitates easy fluid removal.
Implementation Method 1
a fluid permeable membrane extending across the opening
Implementation Method 2
a suction source in fluid communication with the fluid collection device and the fluid collection container

AI summary
An example urinary collection device includes a fluid impermeable barrier defining a chamber, an opening, and an outlet. The opening and the outlet fluid to enter and leave the chamber, respectively. The urinary collection device also includes a fluid permeable membrane extending across the opening. The urinary collection device includes a fluid receiving portion that includes the portions of the fluid impermeable barrier that defines the opening. The fluid receiving portion is configured to be positioned such that the opening is disposed adjacent to the urethral opening of the individual (e.g., a buried penis). The urinary collection device also includes an longitudinal portion extending from the fluid receiving portion. The longitudinal portion is configured to be positioned adjacent to or near the perineum of the individual (e.g., positioned between the thighs of the individual).
